The “hydra” we’re coping with is a metapuzzle: We have now to discover a approach to make use of the options from different puzzles that we’ve already solved to extract yet another reply. If we clear up this one, we’ll be rewarded with extra puzzles.
We all know we have to diagram the solutions for this spherical of puzzles as a binary tree. In line with the hydra metapuzzle’s mythological analogue, each time we clear up one puzzle, two extra department off till we have now a diagram 5 ranges deep. We’re nonetheless lacking solutions from a number of unsolved puzzles that may assist us work out how the diagram works and the way to extract a solution to the metapuzzle. The diagram we’ve drawn, in inexperienced chalk, will get extra chaotic with each addition, erasure, and annotation we squeeze onto the overcrowded chalkboard. However we will sense that we’re only one “aha!” away from an answer.
MIT’s Thriller Hunt has been difficult puzzle lovers yearly since Brad Schaefer ’78, PhD ’83, wrote 12 “subclues” on a single sheet of paper as a problem for mates throughout Unbiased Actions Interval (IAP) in 1981. The solutions led solvers to an Indian Head penny he had hidden on campus. Right now’s Hunts are nonetheless constructed round that primary idea, however what constitutes a problem has modified over 4 a long time. One of many clues from the unique 1981 Hunt is only a lacking phrase in a quote: “He that performs the king shall be _____; his majesty shall have tribute of me.” It’s straightforward to resolve immediately with Google, however in 1981, even in the event you knew it was Shakespeare, in the event you didn’t discover the refined trace that you must search for a personality referring to a play throughout the play, it might need taken a couple of hours of skimming the Bard’s collected works to search out the reply.

We add a couple of extra options to the hydra diagram over the subsequent few hours. Finally somebody notices that each one the solutions within the fifth degree of the diagram appear to have an odd prevalence of Ls and Rs. That is the “aha!” second: They inform us the way to navigate the binary tree. From the primary node on the prime of the tree, we comply with the Ls and Rs within the order they seem in every of the 16 options on the fifth degree. Take the left department, then proper, then left once more, touchdown on a phrase that begins with H. The second fifth-level reply leads us to a phrase that begins with E. Repeating the method with all 16 solutions spells out an apt approach to take care of a hydra: “HEADTOHEADBATTLE.” (Puzzle options are historically written in all caps with no areas or punctuation.) These of us who’ve been tackling the puzzle take a second to get pleasure from our victory earlier than splitting as much as discover new puzzles to work on.
Some parts of the Thriller Hunt are arduous to explain, the form of must-be-seen ingenuity that additionally evokes hacks on the Nice Dome and any variety of above-and-beyond engineering tasks showcased round campus yearly. A lot of the puzzles are completely distinctive, though they do typically incorporate logic and phrase issues in addition to extra mainstream parts like crosswords, sudoku, and Wordle. However virtually something will be became a puzzle. For instance, chess puzzles could be mixed with the cardboard sport Magic: The Gathering. Or solvers might be requested to prepare a Git repository with 10,000 out-of-order commits (that’s, discover the proper sequence of 10,000 modifications to a file because it was tracked in a model management system), determine duets from musicals, or draw on their data of popular culture trivia.
For many of its historical past, the Thriller Hunt had little official standing on campus. By custom as a lot as any organizational effort, groups merely confirmed up in Foyer 7 on the Friday earlier than the Martin Luther King Jr. vacation for the kickoff. In 2014, the MIT Puzzle Membership was shaped to assist present year-to-year continuity and different help, reminiscent of securing rooms for groups to work in and reserving Kresge Auditorium for the opening ceremonies. Puzzle Membership additionally hosts different occasions, reminiscent of mini puzzle hunts and sudoku and logic puzzle competitions—which Becca Chang ’26, the membership’s present president, says “has helped so much with outreach to new college students or anybody who could be curious about [puzzles].”
Know-how has enabled the Thriller Hunt to develop and evolve in important methods, and never simply by way of the sorts of puzzles which are potential. By the mid-Nineties, a single individual might tackle the accountability of writing and working the occasion. Right now it’s a yearlong dedication for the profitable workforce to design the subsequent yr’s Hunt. Doing so requires managing artistic output and technological infrastructure that rival these of a small enterprise. Duties embrace spending hundreds of hours writing and testing puzzles, developing bodily puzzles and props, and constructing a dynamic web site that may face up to the massive inflow of puzzle-hungry guests.

Simply organizing a workforce of solvers generally is a main endeavor, particularly now that an increasing number of individuals are becoming a member of remotely. Anjali Tripathi ’09, who began the workforce I’m Not a Planet Both in 2015, bought her introduction to puzzle hunts by way of a miniature Thriller Hunt that Simmons Corridor runs for first-years. After tackling the principle occasion with the Simmons workforce on campus as an undergrad, she participated remotely for the primary time in 2010. “I used to be overseas in England and nonetheless needed to do Hunt, and I keep in mind how arduous that was,” she says. The workforce “had no infrastructure for it.”
